The audio landscape in the U.S. is vibrant and evolving. Traditional terrestrial radio still maintains a significant share of listenership. Plus, streaming services and podcasts continue to see impressive growth, driving digital audio ad spending beyond $13 billion.
Radio’s Enduring Influence
Despite the rise of digital audio options, terrestrial radio remains an important and influential medium. Traditional radio advertising spend is expected to stay relatively flat as ad spending shifts toward digital audio and programmatic buying. But, the platform continues to command a loyal audience and offer unique opportunities for advertisers.
Streaming Audio’s Ascent
Audio streaming services are experiencing remarkable expansion, diversifying content offerings, and attracting growing listener bases across demographics. This surge in streaming audio consumption is fueling an increase in digital audio ad spend. It’s becoming a crucial component of the modern audio ecosystem.
Podcasting’s Powerful Potential
Podcasting has emerged as a dynamic force as well. It provides opportunities for both direct response and branding campaigns. As listeners engage deeply with podcast content, marketers are leveraging this intimate medium to connect with highly targeted audiences.
Tuning In to the Audio Landscape of 2025
Audio advertising is undergoing significant transformation, which should be taken into account for your 2025 marketing strategy. While traditional radio remains a stalwart in the media landscape, its dominance is gradually waning. Millions of Americans still tune in daily, particularly during commutes. However, the rise of digital audio platforms like podcasts and streaming services is reshaping the industry.
The Challenge of Digital Disruption
- Competition from Digital Audio: Terrestrial radio faces increasing competition from digital audio platforms, offering targeted advertising opportunities and sophisticated measurement tools.
- Measurement and Attribution: Traditional radio relies on ratings and surveys for measurement which can be difficult to quantify the precise impact of ad campaigns. In contrast, digital audio platforms provide granular data on listener behavior and ad performance.
- Shifting Demographics: Younger demographics in particular, are increasingly turning to on-demand audio and spending less time with traditional radio.
This evolution presents both challenges and opportunities for advertisers. While terrestrial radio still offers a broad reach, digital audio platforms provide more targeted and measurable advertising opportunities.

The Rise of Streaming Audio
Streaming Audio Consumption and Spending
Streaming audio continues its rapid growth into 2025. Engagement across platforms like Spotify and Apple Music is rising, and podcasts are becoming more and more popular. With digital audio ad spending projected to surpass $7.5 billion in the U.S., programmatic and podcast ads are leading the way. These advertising channels offer brands more targeted and creative opportunities than ever before.
Streaming audio plays an increasingly important role for advertisers in their marketing campaigns. They offer a number of advantages for advertisers, including:
- Programmatic buying: Programmatic buying allows advertisers to buy ad inventory from multiple publishers with a single platform. Frequency control can be modulated with other digital channels running in the same DSP.
- Audience targeting: Streaming audio platforms offer a high degree of audience targeting. This precision allows advertisers to reach their target audience with specific and relevant ads based on demographics, interests, and even listening history.
- Brand awareness and recall: According to a recent study (Dentsu), streaming audio ads are more likely to be remembered than other types of ads. These ads are more immersive and can create a stronger emotional connection with the listener.
- Measurability: Streaming audio ads are highly measurable. Advertisers can track the performance of their campaigns and make data-driven adjustments as needed.
It’s been proven that audio is an effective media vehicle for advertising to specific audiences. Streaming audio is no different. Scale Marketing views streaming audio as an increasingly important part of a media strategy for many clients.
The Podcast Boom

Younger listeners have traditionally been the primary drivers of podcast listenership. However, the audience is expanding to include older demographics as well. In fact, the 35-54 age group is now the fastest-growing segment of podcast listeners.
The Rise of Podcast Advertising
The popularity of podcasting has led to a surge in advertising opportunities. The platform offers high engagement rates and the ability to deliver messaging through a variety of tactics including:
- Host-Read Ads: These personalized ads are read by the podcast host. Like endorsements on terrestrial radio, they offer an authentic and impactful way to connect with listeners.
- Dynamic Ad Insertion (DAI): DAI technology allows advertisers to target specific audiences with relevant ads, improving campaign effectiveness.
